In booth 2405 at the Optical Fiber Communication/National Fiber Optic Engineers Conference (OFC/NFOEC 2013) in Anaheim (19-21 March), fiber-optic communications component and subsystem maker Finisar Corp of Sunnyvale, CA, USA is demonstrating several new technologies for datacom applications, including two 100G CFP2 modules, that improve port density and flexibility in high-performance optical networks.
CFP2 high-density 100G modules:
Finisar is demonstrating two new optical transceiver modules enabling high-density single-mode and multi-mode 100G ports using the new CFP2 multi-sourced 100G module form factor.
For single-mode fiber applications, the 100GBASE-LR4 CFP2 module supports 100 Gigabit Ethernet (100GE) links up to 10km using 4x28G distributed feedback (DFB) lasers, with a power dissipation of less than 8W maximum and 6W typical, which is significantly lower than electro-absorption modulator laser (EML)-based solutions and enables higher-port-density systems. The module meets IEEE 802.3, OIF and OTN standards, interoperates with existing 100GBASE-LR4 CFP modules, and is expected to be in full production later in 2013.
For multi-mode fiber applications, the 100GBASE-SR10 CFP2 module supports 100GE links up to 150m. It also supports 10G Ethernet fan-out applications, interoperating with either 10x 10GE-SR SFP+ modules (up to 300m links) or with 2x 40GE-SR4 QSFP+ and 2x 10GE-SR SFP+ modules, enabling 100% bandwidth utilization. Based on 10x10G vertical-cavity surface-emitting lasers (VCSELs) and supporting digital diagnostic monitoring functionality, the module offers maximum power dissipation of 3.5W and interoperates with 100GBASE-SR10 CFP modules.
Highest-density 25G embedded optical engine:
With the Parallel 25G BOA (board-mounted optical assembly), Finisar is demonstrating 24 channels supporting more than 600Gbps between transmitter and receiver modules. The Parallel 25G BOA offers what is claimed to be the smallest footprint available in a transceiver, is suited to board-to-board interconnect and optical backplanes, and supports protocols ranging from 1Gbps to 28Gbps per channel including (but not limited to) Ethernet, PCIe, InfiniBand, and Fibre Channel.
4 x 10G parallel single-mode QSFP+ using 1310nm VCSELs: By transmitting four independent long-wave 10Gbps signals on parallel single-mode fibers to separate SFP+ modules, a single QSFP+ module can provide extremely high-density 10Gbps links in data-center deployments. The use of long-wave VCSEL technology makes the single-mode module complementary to existing short-reach multi-mode QSFP+ modules, and the use of standard wavelengths makes it interoperable with the installed base of long-wave 10GBASE-LR transceivers.
